Another object'of the invention'is to provide means whereby the blank is accurately shaped and a suitably prepared for blowing.

Another object of the invention is to provide means whereby adjustments of various parts may be made with the required accuracy and with a minimum of disturbance of the machine as a whole. a Another object of the invention is to mount the apparatus for rotation about a vertical axis and tilting about a horizontal axis for the purpose of dipping the parison molds into the glass in a new and improved manner.

Other details ofthe invention will appear as the description proceeds.

The apparatus asa whole relates to that class where blank molds and blow molds are mounted upon a turret rotatable about a central column.

In this apparatus the blank molds are mounted stationarily with respect to the turret, except for opening and closing, and the blow molds are mounted in one plane which is above the plane of the parison molds. The parisons are raised upward from the parison molds to a level with the blow molds and theblow molds are moved'outward J radially and closed about the parisons and then returned to an inward position beneath blow heads where the articles are blown.

.One embodiment of the invention is illustrated in the accompanying drawings which form a part of this specification. In those drawings,

Fig. 14 is a plan view of the cams for controlling the air pressure to the various parts, the cam rollers controlled by the cams being indicated somewhat diagrammatically;

Fig. 15 is a diagram showing approximately the relative timing of the various portions of the apparatus.

The machine shown is mounted upon wheels 20 and 2| which run upon tracks 22 and are connected by shafts 23. Side frames 24 are suspended from shafts 23 by arms 25. Between side frames 24 midway between the wheels, there is aoentral cross-piece 26. A vertical shaft 21 is mounted in a socket 28in the cross-piece. On the upper threaded end 29 of shaft 21, there is a nut 30. Links 3| connect nut 30 with the ends of levers 32 and 33.

A base 34 has downwardly projecting brackets 35 which are pivoted upon a shaft 36 which is mounted intermediate between the ends of lever 32, the forked outer end of which is pivoted upon shaft 23. Similarly mounted in lever 33 is a shaft 31, the lever 33 being pivoted at its forked outer end upon the other shaft 23. A supporting ring 33 is mounted upon a ball bearing 39 on shaft 37. A cam 40 on a shaft ll journaled in base 34 bears upon supporting ring 38. The cam is shown as being integral with the shaft, but obviously might be a separate member mounted on the shaft, and if desired the mounting could be eccentric, to adjust the throw of the cam.

An adjusting motor 42 is mounted upon a bracket 43 pivoted on the central cross-piece 26. The motor drives a chain 44 which in turn drives a worm 45 meshing with a worm wheel 46 fast upon shaft 21. The upper ends of arms 25 are provided with brackets 41 for a purpose which will be described later.

As will be seen, base 34 is supported upon shafts 36 and 31 carried by levers 32 and 33 and when worm 46 is driven by reversible motor 42 in the desired direction, the inner ends of levers 32 and 33 are raised or lowered as desired, thereby determining the elevation of the base.

Upon base 34 on the end over shaft 36, there is a gear box 50, the gearing in which may be driven by a drive wheel 5|. A chain 52 or other suitable connection is driven by the gearing within gear box 50 and drives a shaft 53 to operate the gearing within a gear box 54. A shaft 55 driven by the gearing within box 54 projects downwardly therefrom and is provided with a. universal joint 56 to take care of any slight lack of exact registry between the gear box and the bearings of shaft 55 in base 34. At its lower end, shaft 55 is provided with a bevel gear 51 meshing with a bevel gear 50 on shaft 59 journaled in the lower side of base 34. At the other end of shaft 59, there is a bevel gear 60 which meshes with a gear 6I on the end of shaft 4| and thereby drives cam 40.

Spur gear teeth 62 are provided upon the flange of gear 20 and mesh with a gear 63. A shaft 64 is mounted in brackets 41 and driven by a crank handle 65.

It will be seen that by operating the handle 65, wheels 20 may be driven to move the machine along tracks 22. In the normal operating position of the machine, the wheels 20 ar positioned against stop 66. When desired, the machine is moved away from the glass furnace towards the right end of tracks 22, as shown in Fig. 2, there being provided stops 61 to prevent movement of the wheels beyond the end of the track.

A cylinder 60 is pivoted at 69 upon a side frame member 24. A piston, not shown, within the cylinder is provided with a piston rod 10 pivoted at H to the bearing of shaft 59 on the lower side of base 34. The cylinder may be provided with air under pressure through a pipe 12. This cylinder is not necessary, but may be employed, if desired, to support the major portion of the weight of the machine and reduce the lifting force which has to be exerted by cam 40. It will be understood that air under substantially constant pressure is provided through pipe 12 and acts as a continuous lifting force in the cylinder. If desired, the pressure provided through pipe 12 might be varied in timed relation with the operation of cam 40, or it might be used to oscillate the base and the cam could be omitted, but the operation first described is preferred. The side frames may be spaced by rods 13, if desired, so as to keep them in proper lateral position.

Upon base 34, there is mounted the stationary central column 15, the upper end 16 of which is cored out for providing vacuum and air pressure channels as will be described later. Mounted upon the central column there is a lower spider 11 and an upper spider 10 which are connected by posts 19. Above the upper spider there are air control rings 00 from the lower of which rings arms 6i extend to the upper spider.

Upon the lower spider there is mounted drive gear a: which is in mesh with a ear 83 t e amassa upper end of a shaft 04 driven by the gearing within gear box 54. If desired, this may be the upper end of shaft 55.

Upon the lower spider 11, there are mounted parison molds and blow molds. The blank molds are mounted within holders 9| at the ends of arms 92 pivoted at 93 on the lower spider. The arms extend at beyond the pivot and are connected by yieldable links 48 to a slide 96 provided with a cam roller 91 which bears against a controlling cam 90 upon a cam plate 99 mounted upon the base of the stationary central column.

On the upper side of the lower spider there are mold carrier slides I00 which are movable radially of the spider in slideways IOI therein. Upon each slide there is mounted a cam roller I02 which works within a groove in cam I03 mounted upon a cam drum I04 which in turn is mounted upon the stationary central column above the lower spider. Blow mold halves I05 are mounted in holders I06 on arms I01. The arms I01 are pivoted at I00 upon the slide I00. A fork I09 is connected by links IIO to. the mold holding arms. The fork slides upon a support I I I and has therein a slideway II 2. Mounted in the slideway II2 there is an operating slide I I3 which has mounted thereon a cam roller I I4. The cam roller is operated by a groove in cam II5 which is mounted adjustably upon cam drum I04 and also is provided with a supporting arm II6 ad- .iustably mounted in a groove H1 in the stationary column. Cam H5 is connected to arm II6 by a bolt and slot connection II6. A spring H9 is interposed between slide I I3 and fork I09 50 that the fork is yieldably driven in mold closing direction while it positively moves in the opening direction.

A blow mold bottom I20 is mounted in a carrier I2I pivoted at I22 on slide I00. The carrier I2I is forked and the branches or arms I23 of the fork are mounted upon pivot I22. The arms of the fork rest upon a cross pin I24 which is mounted in the lower end of mold pivot pin I00. The ends of pin I24 slide in vertical slots in cars I25 projecting downward from support I00. Springs I26 normally hold cross pin I24 and mold pivot pin I00 in its upper position. A bell crank lever I21 is pivoted at I 28 adjacent the upper end of pin I00. One of the arms I29 of the bell crank lever normally overlies the upper end of pin I 08, and the other arm of the bell crank lever carries a cam roller I30 which is operated by a cam I 32 mounted upon the upper side of cam plate H5.

A discharge chute I35 is pivoted at I36 to the lower spider. A spring I31 normally tends to swing the chute to a position where it slants outward, the spring holding the chute outward against a stop I 30. The chute is provided with an abutment I33 which is adapted to be contacted by an abutting screw I40 upon the gathering head as will be described later.

The gathering head comprises a cross-piece I50 having ears I 5I and I52 which slide upon posts 19. A link frame I53 connects the cross head with a lever I54 fulcrumed upon the upper spider at I55. An adjustable link I56 is pivoted at I51 to an upwardly extending arm of lever I54 and is pivoted at I56 to a lever I59 fulcrumed upon the spider at I60. The lower end of lever I53 carries a cam roller I6I which is actuated at proper intercontrol head I64 through which vacuum or air under pressure may be supplied as will be described later. Mounted upon the outer side of head I64 is a pivot I65 for neck ring carriers I66 which carry neck ring halves I61. I

These neck ring halves cooperate with a plunger I16 to form the neck of the article. Plunger I16 is removably mounted upon a vertically reciprocable rod I1I which is pivoted at I12 to a link I13 which in turn is connected to a piston rod I14 slidably mounted in a cross-piece I15 between the side members of the link frame I53. The upper end of rod I14 is connected to apiston I16 within a cylinder I11 which may be supplied with air under pressure by means which will be described later. Upon rod I14 beneath cylinder I11 there is aflixed a collar I18, and a spring I19 between cross-piece I15 and collar I18 normally urges the piston rod upward. The pivot I12 is in line with Slidebars I84 are connected by rods I65 and I86.

To the ends of rods I85 there are connected tension springs I81 normally urging the bars in the direction to close the neck ring. One of the springs I 81 is mounted in the plate I88 on block I63, which 'plate carries abutment screw I46 mentioned above.

Mounted underneath the outer part of spider 18, there is a bracket I96 to which is pivoted a link I9I adapted to abut against cross bar I86 when the neck ring is to be opened, as shown at the right of Fig. 1-. To link I9I there is pivoted an arm I92 connectedby a rod I93 to a lever I94 fulcrumed on a bracket I98 on theupper spider at I95. The lower end of lever I94 carries a cam roller I96 which is actuated by a cam I91 to open the neck ring against the tension of springs I 81,

I as indicated at the right of Fig. 1.

The air control head I64 is provided with a connects with the hollow interior of a column 19 I through an opening in the side thereof. Downward passages 262 lead from passage 266 to the upper end of the neck ring. There is also a chamber 263 in the head which is connected by a passage 264 through an opening 265 with the interior 266 of the other column 19. The chamber 263 is connected by a passage 261 with the upper end of the neck mold. In this way the interior openings in the hollow column 19 are connected with the upper end of the neck ring when the neck ring is in its lower position, as shown in Fig. 10 and at the left of Fig. 1.

' The column 19, shown at the right in Fig. 10 and connected with passage 26I, has an opening through its upper end registering with a passage 268 in upper spider 18, as indicated in 'Fig. 6. Passage 268 registers with passage 269 in hollow arm 8| and thereby connects with an annular chamber 2I6 which is always in communication with a passage 2 in the central column portion 16 and which is connected by any suitable means with a source of vacuum.

The communication between passage 266 and the interior of the column 19 is controlled by a valve 2I2 which is normally held closed by a spring 2I3. Tappet 2I4 overlies the upper end of the stem of valve 2 I2 and is actuated at suitable intervals by a link 2I5 connected to a lever 2I6 pivoted at 2" on the outer side of ring 86. The lower end of lever 2 I6 carries a cam roller 2I8 in position to be actuated at suitable times by a cam 2I9 mounted upon the upper side of a cam plate 226 which is secured to central column 16 above spider 18.

The upper end of the hollow column shown at the left in Fig. 10 is connected by suitable means, not shown, with an opening into a valve chamber mounted on ring 86. This valve chamber, valve and operating means are not shown in detail on the drawings, but their position is indicated diagrammatically on Fig. 14, and their details are the same as those for the other air controlling valve. In the construction shown at the left of Fig. 1, there is shown an opening 22I which is connected by means, not shown, with the blow head for the blow mold, described below. This opening.22l in a valve chamber 222 communicates through valve 223 with a chamber 224 in ring 86 which in turn is supplied with air under pressure through a chamber 225 in the central column 16.

A spring 226 normally holds valve 223 in closed position A lever 221 overlies the upper end of the stem of valve 223 and is pivoted at 228 to a bracket 229 on the valve chamber. A cam roller 236 on the outer end of lever 221 passes beneath a cam 23I. This cam is preferably made up of a series of short sections 232 each mounted bya screw and slot connection 233 for vertical adjustment upon a cam carrying plate 234 mounted upon the upper end of the central column 16. By this means air under pressure is admitted to the blow head at proper times and by similar means indicated on Fig. 14, and comprising a valve chamber like 222 controlled by a valve and actuating lever similar to lever 221 having on the outer end thereof a cam roller 235 which is actuated at suitable intervals by cam members 236, similar to cam members 232, air is admitted to hollow column 19and through the column to the neck ring at suitable times.

As shown at the right of Fig. 1, there is a third valve chamber 231similar to chamber 222 and controlled by similar means including a cam roller 239 actuated by the cams 239' shown on Fig. 14. This valve chamber is connected by suitable means, not shown, with cylinder I11.

A blow head 246 is mounted to cooperate with the upper end of the blow mold at suitable times. The blow head is carried upon a rod 24I which is mounted adjustably in the lower end of a sleeve 242. The upper end of the sleeve is provided with a cam roller 244. g

A lever 245 is pivoted at 246 near the outer end of lever I54 and has an actuating surface normally overlying roller 244. The innerend of lever 245 is pivoted to the lower end of a rod 241 which slides in an ear 248 on lever I54 and limits the depression of the lever. A spring 249 mounted about rod 241 normally presses the lever downward. When the outer end of the lever I54 is depressed, this connection yieldingly contacts and depresses the roller 244 and thereby the blow head.

, Mounted upon pivot I55 of lever I54, there isa bell crank lever, one arm 256 of which is in position to contact the under side of roller 244 when lever I54 is raised, as shown at the right of .Fig. 1. The other arm 25I of the bell crank lever has a screw and slot connection 252 with lever I54 so that the relation of arm 256 to lever I54 may be adjusted to raise the blow head at the desired time.

Means are provided for cutting off the glass from beneath the parison mold at suitable intervals. This means comprises a cut-off member 260 (see Fig. 6) which is supported by an arm 26I on the lower end of a shaft 262 (see Fig. 1). Shaft 262 is adjustably suspended from a connector sleeve 263 by means of a screw thread 264 and hand wheel 265, shaft 262 being splined in connector 263 and the hand wheel being rotatably supported by the connector so that the height of the cut-off can be adjusted by turning the hand wheel. Connector 263 has attached to its upper end a collar 261 which is above the upper spider. From collar 261 there project pins 266 sliding-in grooves in the outer ends of a yoke 268 mounted on the outer end of a lever 21B fulcrumed at 21I upon a bracket on the upper spider. The other end of lever 210 is connected by means of a link 212 to a lever 213 pivoted at 214 upon ring 80 and carrying at its lower end a cam roller 215 adapted to engage a cam 216 attached to cam plate 220.

Connector 263 is splined through a gear wheel 211 mounted on the upper spider and which meshes with a rack 218 slidable radially of the apparatus. Slide 218 is connected by a yielding connection 219 with a slide 280 which carries on its bent rear end a cam roller 28! working in cam groove 282 in a cam member attached to the lower side of cam plate 220.

It will be seen that the elevation of the cutter may be adjusted at any time by hand wheel 265 and that its vertical position is controlled in timed relation with the operation of the apparatus by means of cam 216 and that the shaft is oscillated as desired by cam track 282.

The details of the cam construction have not been dwelt upon in detail, but it will be readily seen that cam drum I04 may be positioned as a whole about the central column carrying with it in adjusted relation the cams for operating the blow mold, also the cam I62 for controlling the raising and lowering of the neck ring and the blow head and the opening of the neck ring. In this way, all of the mechanism for transferring the blank to the blow mold may be adjusted about the central column without interferring with the timed relation of the various movements. At the same time, the cams for operating the various devices are each separately adjustable.

Similarly adjustment of plate 220 about the central column would carry with it adjustment of the cams for controlling the cut-off and the vacuum without disturbing the relative positions of the cams 2| 9, 216 and 282 which are in turn separately adjustable when desired. In like manner, the top cam plate may be adjusted as a whole to position the air control cams about the central column without disturbing their relative adjustment while each of the air control cams is separately adjustable as to length, degree of opening at any one point and position relative to the other blow control cams simply by vertical adjustment of the separate sections of the controlling cams or by entire removal thereof, if desired.

The operation of the device has been indicated to some extent in connection with the description of the several portions of the apparatus, but for convenience the consecutive operations of the devices for gathering and blowing the glassware will be briefly described.

By turning handle 65, the apparatus is moved along track 22 against stops 66, which are positioned so as to insure proper relation of the apparatus to' a receptacle for molten glass. Handle 65 may be used to move the apparatus away from the glass recepacle for convenience in changing molds or for any other purpose.

The length of the molds varies with the articles to be made. In all cases the mold tops must .cooperate with the neck rings, so the variation vacuum chamber 2| I is connected with the top of the neck ring and parison mold so as to suck glass upward into the parison mold. It will be readily understood that at this time the parison in question is positioned above a suitable pool of glass, and the lower portion of cam 40 rests upon supporting ring 38 so that the base and entire apparatus mounted thereon are tilted towards the glass gathering side of the apparatus sufliciently to dip the lower end of the parisonmold into the molten glass, so that a suitable chargeof glass is'insured. As the turret continues to revolve, and in timed relation thereto, tilting cam 40 is rotated and raises the glass gathering side of the apparatus so that the lower end of the parison mold is raised above the surface of the glass.

Thereupon, the cut-off device is operated to swing across the bottom of the blank mold and cut off the glass.

In the preferred construction, as shown, the parts are proportioned so that the axis of the turret is vertical when the cam is in the position in which it is shown in Fig. 2, but the apparatus would operate similarly if the apparatus were tilted somewhat away from or toward the glass receptacle. The normal position of the axis need be only approximately vertical.

The turret continues to revolve, carrying the parison mold beyond the gathering pool and at the proper time the cam 216 lowers the cut-off knife slightly, and in timed relation therewith air is released from cylinder I11 so as to allow spring I19 to raise plunger I10 and air is admitted through the left hand column 19, as viewed in Fig. 10, to form preliminary blow opening in the blank, the cut-off knife remaining in position a slight distance below the blank so as to limit the elongation of the blank at this time.

Thereafter, the knife is retracted, the blank mold is opened and the neck ring and the cross head carrying the same are raised by cam I62.

With the blank raised and the blank mold opened, the blow mold likewise is opened. Bottom I20 is" tilted by lowering of mold pin I08 so as to discharge the previously blown glass and chute I35 is swung to its outward position between the opened halves of the blank mold so as to guide the blown bottle to a position beyond the blank mold where it may be received and conveyed away in any desired manner.

After the blown bottle is discharged, the blow -mold carrying slide is moved outwardby cam I03 that reaches normal position, but if desired, the apparatus might be arranged so that the bottom of the neck ring would be in line with the top of the blow mold at this time and bottom I20 would be brought up against the bottom of the blank. As stated, however, it is preferable to have the neck ring raised slightly higher than the top of the blow mold at this time and lowered just before the blow mold is closed. This squashes the bottom of the parison onto the mold bottom and facilitates proper formation of the article.

- Cam I91 operates to open the neck ring as the blow mold is closed. This may be timed as clesired. It is convenient to open the neck ring slightly before the completion of the closing of the blow mold so as to avoid the necessity of exact registration, but obviously the neck ring and blow mold may be accurately aligned so that the neck ring may be opened after the closing of the blow mold or just at the completion of the closing of the blow mold.

After the blow mold has closed and the neck ring has opened, the blow mold carrying slide is returned to its inner position in line beneath the blow head. Thereupon, the neck ring carrying cross head is lowered and member 245 presses the blow head down upon the blow mold. This returns the parts to the relative position in which they are shown at the left of Fig. 1, and the blowing of the article in the blow mold proceeds, being controlled by the adjustment of the cam which governs the admission of air into the blow head. It will be readily seen that the parts remain in this position until after the next blank has been sucked up into. the blank mold in the manner previously described, the blow head being raised only after thenext blank has been formed in the blank mold and concurrently with the raising of that blank. The blowing, however, may be stopped as soon as the blown article has set sufficiently to allow the release of the pressure. Also, it will be readily understood that the blow mold may be opened for a time, if desired, before the bottom is tilted to discharge the bottle.

Suitable means are provided for cooling the various parts and, as indicated in the drawings, the lower end of column 15 is hollow and may be supplied with cooling air, and from thence the air may be taken through the hollow lower spider for cooling purposes as desired. The exact arrangement of the cooling means may be modified as desired and as found advisable to achieve the necessary cooling of the parts in the time re quired.

The arrangement by which the discharge chute is held resiliently in discharge position is not only convenient because it makes possible a simple arrangement for pushing the chute back out of the way during the gathering operation, but it is also advantageous because it provides a yielding surface onto which the blown articles are dropped, thereby lessening the wear on the chute and the danger of injury to the blown articles.
